4 Claims.

My invention relates to a new and improved umbrella.

One of the objects of my invention is to provide an umbrella which hascertain improvements in construction, over the umbrella shown in U. S.Patent No. 1,911,784 issued on May 30, 1933.

Another object of my invention is to provide an improved construction atthe inner or handle part of the umbrella.

Another object of my invention is to provide an improved constructionfor the sectional ribs of the umbrella.

Another object of my invention is to provide a new and improved meansfor connecting the runners, to the sectional ribs of the umbrella.

Another object of my invention is to provide a new and improved devicefor connecting the portions of the sectional ribs of the umbrella toeach other.

Other and additional objects of my invention will be set forth in thefollowing description and drawings, which illustrate a preferredembodiment of the invention.

Fig. 10 is a sectional View on the line lili9 of Fig. 9.

Fig. 11 is a detail elevation of an upper or inner rib section.

The improved umbrella comprises a pair of telescopic stick sections la.and lb. The upper or outer stick section la. is tubular, and the innerstick section ib is also tubular, and it is slidably mounted Within theouter stick section la..

As shown in Fig. 1, the inner stick section lb is provided with a slot,in which a detent or catch 2 is located. Asshown in Fig. 1, this detent2 is provided with a metal shank 2a, which is resili- 1935, Serial No.26,942

ent, and which ts and is held frictionally within the adjacent part ofsaid inner stick section lb.

When the umbrella stick is extended, as shown in Fig. 9, the detent orcatch 2 is moved laterally by the resilient shank 2a so that detent 2engages the lower end of the outer stick section la.. The detent orcatch 2 can be forced inwardly, in the usual manner, in order tocollapse the stick of the umbrella.

The improved construction of the detent or catch 2 makes it unnecessaryto fasten the same to the inner stick section ib, and the frictionalgrip of the shank 2a., keeps said member 2 reliably in the positionwhich is illustrated in Fig. 1, as well as in the position which isshown in Fig. 9.

A tubular runner 3 is slidably mounted upon the outer stick section la.,and the upper or outer stick member la is provided with the usual springdetent or catch 23, in order to hold the runner 3 in its upper position,which is illustrated in dotted lines in Fig. 9. If desired, the runner 3could have a vertical slot, closed at both ends, above the bottom of therunner, and catch 23 could project through said slot, when the runner 3is in its upper position.

As shown in Fig. 1, the spring detent 23 is connected to a ring 24. Forthis purpose, the spring detent 23 is provided with a head H, which ispartially located in an opening 29, which is provided in the upper stickmember la. An opening 25 is also provided in the upper stick member ia,so that the detent 23 can be moved inwardly, in order to release therunner 3, if it is desired to collapse the umbrella.

The collar 24 is suitably connected to the upper stick section la.

The runner 3 is provided with spreaders il, which are pivotallyconnected thereto, and said spreaders i are also pivotally connected tothe upper rib sections 5a.. The spreaders d are preferably made oftempered and springy metal of solid cross section, like the ribsections.

The spreaders i are pivotally mounted in recesses of the runner 3, bymeans of a wire ring 5, which passes through suitable openings in thelower ends of said spreaders. The general details of construction whichare not specically mentioned herein, are shown in said U. S. Patent No.1,911,784.

As shown in Fig. 1, the upper end oi the upper stick member la isprovided with a collar 3, which is suitably connected to said stickmember ia. This connection can be by means of a drive iit, or by anyother suitable means.l Said collar 8 has an upper flange, which isexternally threaded. A stop-head 5l) is located at the upper end of thestick member Ib, and this member 5i! is provided with an enlarged head,as shown in Fig. 1. A head It has an internal thread, by

means of which it can be screwed into the position shown in Fig. l.

When the stick is extended by moving the inner stick-member ibdownwardly, the head 50 enters the outer stick memberla, since head 50moves in unison with inner stick member Ib. In the extended position ofthe stick, head 50 is below catch 23. The head 56 makes it impossible topush the inner stick member upwardly, while the spring catch 23 is heldinwardly. If theoperator attempts to do this, the head 56 strikesagainst spring 23. If the top of the tubular inner stick member is open,it is possible to have the rim of the inner stick member engage thecatch 23, and either break or bend the catch.

This head Il! serves to clamp the upper end of the fabric covering C` ofthe umbrella.

In this improved construction, each of the upper rib sections 5a, isprovided with a twisted head part 53. This twisted head part 53, isgenerally perpendicular to the body of said ribsection 5a. The twistedhead part is made by twisting the upper end of the upper rib section,through an angle of 90. Said upper rib section has a solid rectangularcross-section. Each twisted part 53 of the rib section 5a is providedwith a bore or opening, and a wire ring 9, which is located in asuitable groove of the collar 8, serves to connect the rib sections 5a.in a turnable manner, to said collar S. By making the rib sections 5a.of integral construction, and by twisting their upper ends in the mannerindicated, a very sturdy and reliable and cheap construction isprovided.

As shown in Fig. 7, the lower end of each rib section 5a, is providedwith a channel member 55, which is connected to said rib section 5a bymeans ci a fastening member 55. As shown in Fig. 7 and Fig. 8, thechannel member 55 is provided with perforated ears 51. As shown in Fig.8, each lower rib section 5b is connected to said ears 57, by means of apivot pin 58. This channel member 55 limits the turning of the ribsection 5b, relative to the rib section 5a, and when the ribs are in theextended position shown in Fig. 9, each channel member 55 provides astrong backing for its associated pair of rib sections.

As shown in Fig. 11, each upper rib section 5d is provided with aportion of reduced thickness, thus providing shoulders 54.

Each spreader 4 is provided with a one-piece member 60, which partiallyembraces the adjacent rib section 5a. The shoulders 54 provideabutments, thus preventing any relative longitudinal shift between saidmembers and the rib sections 5a. Said members 6l! are turnably connectedto the spreaders 4 by means of pins 1. As shown in Fig. 8, the ears 5lare provided with inwardly projecting flanges. The upper ends of the ribsections 5b are twisted, like the twisted ends 53 which have previouslybeen described. Said upper twisted ends of the rib sections 5b fitbetween the inwardly directed anges of the ears 51.

Referring to Fig. 1, the lower end of the inner stick member Ib isexternally threaded, and a head 52 is provided with a recess whose wallis internally threaded. The head 52 can therefore be secured to thelower end of the stick member Ib.

'Ihe head 52 is provided with a cup-shaped flange 52a.. A detent 5I isconnected to the inner surface of the head 52. rIhe detent 5! isprovided with separated arms Sla, which are of resilient construction,so that the inwardly directed ends of said resilient arms Sla candetachably engage the corresponding flange of the runner 3, when theumbrella is in the collapsed condition.

When the runner is in its bottom position, the bottom of the runnerextends over the top end of catch 2, so that said catch 2 is movedinwardly, either wholly or partially. Hence the inner stick member canbe pushed into the outer stick member, without further manipulation ofcatch 2. That is, the bottom of the runner projects below the top edgeof the vertical recess which is provided at the bottom edge of the outerstick member, and which catch 2 enters when the stick is extended. Theengagement of catch 2 in said slot prevents any relative turningmovement between the stick members, when they are in the extendedposition.

The bottom end of the outer stick-member (which may be made of aluminum)may be reinforced by a ring of hard metal, such as steel or brass, whichhas a press t on the lower end of the outer stick member. In its lowerposition, the runner passes over said ring reinforcement.

I have shown a preferred embodiment of my invention but it is clear thatnumerous changes and omissions can' be made Without departing from itsspirit.

I claim:

, 1. An umbrella having a rib section of solid rectangular crosssection, one end of said rib section being twisted substantially aroundthe longitudinal axis of said ribsection, relative to the body of saidrib section.

2. A rib construction for an umbrella comprising an upper rib sectionand a lower rib section, said rib sections having bodies of solid andrectangular cross section, the upper end oi the upper rib section beingtwisted relative to the body thereof and around the longitudinal axis ofsaid upper rib section, a connecting member rigidly connected to thelower end of the upper rib section, said connecting member beingprovided with lateral flanges having ears which are provided withinwardly directed flanges, the width of the upper rib section beingsubstantially equal to the distance between the adjacent walls of saidlateral flanges, the lower rib section having a solid and rectangularcross section, the width of the lower rib section being substantiallyequal to the width of the upper rib section, the upper end of the lowerrib section being twisted relative to the body thereof and being locatedbetween the flanges of said ears, and a pin pivotally connecting saidears to the upper end of the lower rib section.

3. In an umbrella, a runner slidably mounted on a telescoping stick, ahead having a cup-shaped flange mounted on the handle end of said stickin which the lower end of the runner is located when the umbrella iscollapsed, and spring detent means located within said cup-shaped flangeand connected to said head, said spring detent means being adapted toengage said runner releaseably.

4. In an umbrella, a runner, a spreader pivotally connected to saidrunner, a pivotally mounted rib having shoulders intermediate the endsthereof, and a connecting member for pivotally connecting said rib tothe spreader, said connecting member passing at least partially aroundthe rib and having its edges substantially abutting said shoulders.
